Last week we introduced Upsun Dispatch™: a platform for the agentic software development lifecycle, where workflow is the primitive , not the agent. Today, prerelease is open. Starting July 1, a founding cohort of design partners gets early access. This is not a traditional beta. We are looking for engineering teams already running AI workflows and hitting the limits of what individual tools can do: teams who want to help shape what Upsun Dispatch becomes, not just use what we ship. Design partners get direct access to the core team, real input on the roadmap, and charter terms that reflect a genuine partnership rather than a vendor relationship. Apply at upsun.com/dispatch . Read the full announcement: Upsun Dispatch™ is now open for prerelease Starting July 1, 2026, Upsun Dispatch™ is open to a founding cohort of design partners. Here is what joining early means and how to apply upsun.com

If your Terraform plans are slow, your blast radius is too wide, or multiple teams are stepping on each other's changes, it's time to split your monolith. See The Problem with Large Terraform States for how to diagnose whether you've reached that point. This guide walks through the process of breaking a monolithic Terraform state into smaller, focused states — and how Snap CD can manage the dependencies between them so you don't have to. The approach 1. Identify natural boundaries Look at your resources and group them by lifecycle and ownership. Common boundaries: Networking — VPCs, subnets, route tables, NAT gateways. Changes rarely, underpins everything. DNS — Zones, records. Usually owned by a platform team. Compute — Kubernetes clusters, VM scale sets, container services. Changes more often, depends on networking. Application infrastructure — Databases, caches, queues, storage accounts. Owned by application teams. Monitoring — Dashboards, alerts, log sinks. Changes frequently, depends on everything but nothing depends on it. A useful test: if two resources would never be changed in the same PR by the same person, they probably belong in different states. 2. Map the dependencies Before you move anything, draw the dependency graph. Which groups produce values that other groups consume? networking dns │ ▲ ▼ │ compute ──────────►─┘ │ ▼ application │ ▼ monitoring The outputs that cross these boundaries are what you'll need to wire up after the split. Typical examples: Networking → Compute: vpc_id , private_subnet_ids Compute → DNS: load_balancer_ip Compute → Application: cluster_endpoint , cluster_ca_certificate Application → Monitoring: database_id , cache_name 3. Use terraform state mv to migrate resources Terraform's state mv command lets you move resources from one state to another without destroying and recreating them. # Initialize the destination state cd modules/networking terraform init # Move resources from the monolith to the new state terraform state mv \

At some point every growing Terraform project hits a wall. Plans that used to finish in seconds now take minutes. Applies feel risky because hundreds of resources share a single blast radius. Colleagues avoid running terraform plan because it hammers cloud APIs hard enough to trigger throttling. The state file itself becomes a liability — large, slow to lock, and one bad write away from corruption. This guide covers the symptoms of an oversized state, the band-aids teams reach for, and the structural fix that actually works. How Terraform state works under the hood Every terraform plan does two things: Refresh — for every resource in state, Terraform calls the provider's API to read the current real-world status. A state with 500 resources means 500+ API calls, often more when resources have nested data sources. Diff — compare the refreshed state against the desired configuration and produce a change set. The refresh phase is the bottleneck. It's sequential per provider (parallelism helps across providers, not within one), and every resource pays the cost whether you changed it or not. Adding ten resources to a 500-resource state doesn't make plans 2% slower — it makes the refresh 2% slower on every single plan, for every engineer, forever. Symptoms of a state that's too large Slow plans The most visible symptom. Plan time scales with resource count because every resource is refreshed on every plan, regardless of whether its configuration changed. The exact speed depends on provider — AWS resources with complex nested structures (IAM policies, security group rules) are slower to refresh than simple ones, and Azure resources that require multiple API calls per refresh are worse still. These aren't edge cases — users regularly report 2,900-resource states taking 20–25 minutes to plan and 1,600-resource states taking 8+ minutes . Even starting Terraform with a large state can take minutes before a single API call is made . There's a long-standing proposal for terraform

The company may finally be ready to try to deliver on Elon Musk's years-long promise of launching a robotaxi network of its own.

Let's be honest—traditional A/B testing is broken. If you've ever implemented client-side testing, you know the drill. Your users load the page, wait for JavaScript to execute, and then—flicker—the content changes. It's jarring. It hurts your Core Web Vitals. And worst of all, your experiments might be measuring user frustration instead of genuine engagement. But what if you could run A/B tests with zero flicker? What if you could modify your HTML before it even reaches the browser? That's exactly what Cloudflare Workers make possible . The Server-Side Advantage A/B testing at the edge means making decisions about which variant a user sees before any HTML is sent to their browser . Instead of: Load the page Execute JavaScript Flicker Apply the variant Track the result You get: Decision made at the edge Correct HTML streamed immediately Zero flicker Better performance Companies like Ninetailed are already using Cloudflare Workers to achieve 2-3x cost savings compared to traditional serverless platforms, all while delivering personalized experiences with minimal latency . How It Actually Works The concept is surprisingly elegant. Your Cloudflare Worker intercepts incoming requests, checks for a cookie to maintain user consistency, and routes users to the appropriate variant . Here's a simplified version that's production-ready: javascript const NAME = "myExampleWorkersABTest"; export default { async fetch(req) { const url = new URL(req.url); // Determine which group this user is in const cookie = req.headers.get("cookie"); if (cookie && cookie.includes(`${NAME}=control`)) { url.pathname = "/control" + url.pathname; } else if (cookie && cookie.includes(`${NAME}=test`)) { url.pathname = "/test" + url.pathname; } else { // New user—randomly assign them (50/50 split) const group = Math.random() < 0.5 ? "test" : "control"; url.pathname = `/${group}` + url.pathname; // Fetch and modify the response to set a cookie let res = await fetch(url); res = new Response(res.body, res

Recentemente percebi uma coisa meio curiosa: eu simplesmente tinha um problema ao consumir o conteúdo do 4noobs do jeito que ele é organizado hoje. Não porque a organização seja ruim — muito pelo contrário. Acho que a comunidade fez um trabalho incrível organizando o projeto. O ponto é que eu percebi que meu jeito de estudar é diferente: tenho muito mais facilidade quando consigo seguir listas, trilhas ou um caminho de aprendizado mais visual. Foi aí que pensei: "Se esse problema existe para mim, talvez exista para mais alguém. E se, de quebra, eu aproveitar isso para praticar consumo de APIs?" Foi assim que nasceu a Central 4noobs . A proposta era simples: consumir todo o conteúdo disponível no GitHub do 4noobs e apresentá-lo de uma forma que fizesse mais sentido para o meu jeito de estudar, organizando os materiais em listas e trilhas de aprendizado. A ideia nunca foi substituir a organização do projeto original, mas oferecer uma forma diferente de navegar pelo mesmo conteúdo. Essa era a ideia inicial... mas, como acontece com praticamente todo projeto pessoal, ela foi crescendo conforme o desenvolvimento avançava. Mas ainda é uma alternativa . Tenham em mente isso. :) O que aprendi durante o projeto O projeto foi desenvolvido utilizando Next.js , TypeScript , Drizzle ORM e Supabase como banco de dados (e hoje já não tenho tanta certeza se essa foi a escolha mais inteligente 😅). O maior aprendizado foi entender melhor como funciona o consumo de APIs. Antes eu entendia o conceito na teoria (com o próprio 4noobs , inclusive), mas foi durante o desenvolvimento da Central que realmente comecei a compreender como tudo se conecta. Depois desse projeto, passei a enxergar melhor como uma API é estruturada e, principalmente, como consumir seus dados sem simplesmente despejar tudo na tela. Outra parte interessante foi aprender a tratar os dados recebidos. Uma coisa é receber uma resposta gigantesca da API. Outra completamente diferente é filtrar apenas as informações que re

If you've ever wondered how to visualize, teach, or explore keyboards without owning physical hardware, a keyboard simulator is the answer. In this in-depth guide, we explore what keyboard simulators are, how they work, and why they are changing the way people learn to type. Defining a Keyboard Simulator A keyboard simulator is a software application that digitally recreates the visual, functional, and interactive behavior of a physical keyboard. Unlike a simple on-screen keyboard that merely serves as a typing aid, a true keyboard simulator renders the keyboard in detail — often in three dimensions — and responds to keystrokes in real time, creating an immersive and educational experience. The best keyboard simulators go far beyond static images. They animate individual key presses, replicate the visual design of specific keyboard models, support multiple layouts (QWERTY, Dvorak, AZERTY), and even show animated hands performing the typing — making them extraordinarily useful for remote teaching, accessibility testing, content creation, and learning to type. 💡 Did you know? The Keyboard Simulator by Roboticela is one of the most advanced free and open-source keyboard simulators available today, featuring 3D interactive rendering powered by React Three Fiber, five authentic laptop keyboard models, and eight beautiful visual themes. The Core Components of a Keyboard Simulator A fully-featured keyboard simulator typically includes several key components that work together to create a complete experience: 🎮 3D Rendering Engine: Displays the keyboard model from any angle with smooth rotations and zoom capabilities. ⌨️ Real-Time Key Feedback: Every keystroke on your physical keyboard mirrors instantly on the 3D model. 🖐️ Hand Animation: Animated hands show proper finger placement and movement as you type. 📝 Document Editor: A built-in text editor captures your input and links it to the keyboard visualization. 🎨 Theme System: Multiple visual themes make the experience beau
